Abstract
A spectrometer linkage focusing mechanism, an object lens is fixed on an object lens connecting cylinder; the object lens connecting cylinder is arranged in an object lens fixing shell fixed in a shell; grating is fixed on a grating fixing plate hinged on the shell; a focusing knob is arranged at the lower part of the shell for connecting a upper cam and a lower cam; back of the object lens fixing shell is equipped with a spring popped at back of the object lens connecting cylinder; front of the object lens fixing shell is equipped with an object lens focusing plate; upper end of the object lens focusing plate is hinged with the object lens fixing shell; middle part has a push column popped on the object lens connecting cylinder; lower end has a raised head leaning on the peripheral curve of the upper cam; the grating fixing plate is connected with a grating adjustment arm; a pullback spring is connected between the grating adjustment arm and the shell; lower end of the grating adjustment arm is equipped with an adjusting bolt; end of the adjusting bolt leans on the peripheral curve of the lower cam. The utility model realizes the linkage focusing of the coordinated movement between the object lens and grating when rotating the focusing knob to clear the spectral line, simplify the operation and improve the observing quality and efficiency.
Description
Technical field:
The utility model relates to a kind of spectrometer ganged focus device, is used to link regulate the object lens and the grating of spectrometer.
Background technology:
Spectrometer is used in visible-range, by the method for comparison spectrum intensity, metal is carried out qualitative rapidly and semi-quantitative analysis, determines ingredient in the metal, is widely used in industries such as machine-building, metal smelt, thermal treatment, instrument and meter.Its groundwork principle be with a branch of directional light by object lens directive grating, grating is decomposed into monochromatic light with directional light, monochromatic light is reverse again by object lens, arrives eyepiece at last through catoptron, objective lens, just can observe spectral line.But existing spectrometer optical module is independent separately, and when the composition of amalyzing substances was observed spectrum, the wavelength shift of material can make the optic spectrum line sharpness change, must readjust object lens and grating and just can make spectral line clear, and complicated operation, quality and result are observed in influence.
Summary of the invention:
The purpose of this utility model provides a kind of spectrometer ganged focus device, realizes grating and object lens ganged focus, makes object lens follow the variation of grating and change, and reaches and observes each regional spectral line purpose clearly.
The purpose of this utility model realizes as follows: this spectrometer ganged focus device relates to object lens and grating, object lens are fixed on the object lens connecting cylinder, grating is fixed on the grating fixed plate, object lens connecting cylinder device is slidingly matched in the object lens set casing and with its endoporus, the object lens set casing is fixed on the shell, the grating fixed plate middle part is hinged on the shell, the position that is between object lens set casing and the grating fixed plate at outer casing underpart is provided with focusing knob, and focusing knob connects overhead cam and following cam; Spring is equipped with at object lens set casing rear portion, and spring withstands on the rear portion of object lens connecting cylinder; Object lens set casing front is provided with object lens focusing plate, and object lens focusing plate upper end is hinged with the object lens set casing, and the middle part pushes away capital on the object lens connecting cylinder, and the lower end has plush copper to lean against on the overhead cam peripheral curve; Connect the grating regulating arm on the grating fixed plate, be connected extension spring between grating regulating arm and the shell, grating regulating arm lower end is provided with set screw, and the set screw end leans against down on the cam peripheral curve, can correction of deviation by set screw.The rotation focusing knob with the contact point of object lens focusing plate gradually during hole enlargement, promotes the swing of object lens focusing plate on the overhead cam, and object lens focusing plate promotes object lens connecting cylinder band backward and object lens and move, otherwise object lens focusing plate moves forward under spring action; Following cam curve face promotes the grating regulating arm, and the grating regulating arm makes the grating swing, otherwise, the backswing under the extension spring effect of grating regulating arm, the parameter of design overhead cam and following cam is when the rotation focusing knob, make the object lens and the grating coordinated movement of various economic factors, reach the purpose of ganged focus.
The beneficial effects of the utility model are: during the rotation focusing knob, make the object lens and the grating coordinated movement of various economic factors realize ganged focus, make spectral line clear, simplified operation, improved observation quality and efficient.
